Description
Leader of the group Stochastics: Bert Zwart.
Many natural and man-made systems and processes are driven by random phenomena. Examples can be found in areas such as communication, energy, information, logistics, and transportation systems. In order to model, describe, and improve such systems, our group develops and studies probabilistic, operational and statistical models. Our group’s analysis of these models relies on techniques from fundamental probability theory, queueing theory, stochastic scheduling, spatial stochastics and stochastic geometry. Our work with various companies in these areas, as well as with top researchers and universities across the globe, ensures our position at the forefront of every aspect of this research field.

CWI launches spin-off Stokhos Emergency Mathematics
Centrum Wiskunde & Informatica (CWI) announces the foundation of its new spin-off Stokhos Emergency Mathematics. Stokhos provides software solutions which enable the proactive relocation of emergency services based on predictions of future demand.
Mathematical models for optimal coverage of emergency services
Providing proper care in time in emergency situations. This is what emergency services stand for. On 6 June mathematician Pieter van den Berg defends his PhD thesis at TU Delft. He developed models for optimising the logistics of emergency response vehicles.
Increased call center efficiency by identifying redialers
Call centers should base their staff planning on the number of unique callers instead of the total number of calls. Furthermore, introducing a system that gives redialers priority over fresh callers both reduces the average waiting time and improves the fairness of the system. This can be concluded from a study on call center management conducted by CWI.
Firefighters better in position with mathematical model
How could firefighters position themselves even better in a region? If multiple stations are busy fighting a major fire, where should vehicles of other fire stations go to for optimal coverage?

QUEUEING COLLOQUIUM 2018
Start: 2018-05-07 00:00:00+02:00 End: 2018-05-07 23:59:59+02:00
The 2018 edition of the Queueing Colloquium will take place at CWI on May 7.
Lunch is provided, and the day will be concluded with a reception. As usual, participation is free, but we kindly ask to register here, in order to arrange for lunch and drinks. Please do so by April 30 at the latest.
Date: Monday, May 7
Location: CWI, room TBA
Address: Science Park 123, Amsterdam
This edition roughly coincides with the 40-year anniversary of the first edition of the queueing colloquium organized in 1978. To commemorate this fact we have an excellent roster of speakers including:
- Rami Atar (Technion)
- Onno Boxma (TU/e)
- Mor Harchol-Balter (CMU)
- Tolga Tezcan (London Business School)
Times, titles and abstracts to follow. For further information, do not hesitate to contact us.
Best wishes,
Bert Zwart and Peter van de Ven
